From Leah’s text book called Social Psychology: Third Canadian Edition:

Explaining why people believe something says nothing about the truth of their beliefs. That is a logically separate issue. A psychology of religion might tell us why a theist believes in God and an atheist disbelieves, but it cannot tell us who is right. Explaining either belief does not explain it away. So if someone tries to discount your believes by saying, “You just believe that because…,” you might recall Archbishop William Temple’s reply to a questioner who opened the discussion after the archbishop’s address with this challenge: “Well, of course, Archbishop, the point is that you believe what you believe because of the way you were brought up.” To which the archbishop replied: “That is as it may be. But the fact remains that you believe I believe what I believe because of the way I was brought up, because of the way you were brought up.”
